BINDING BOOKS.

SPECIFICATION forming part of Letters Patent No. 239,927, dated April 12, 1881.

i Application nieu June 1, 181s.

To all whom it may concern:

Be it known that I, HUGO BREHMER, of the city and county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Binding Books; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Iiigures l and 2 are perspective views of books containing my invention, and Fig. 3 a section of one of them. j

Heretofore a number of folded signatures or sections composing a book have been sev -eured together by sewing them onto cords resting in saw-cuts in the backs of said signatures or sections, then applying glue to said backs and cords, and then, before the glue is cold, attaching a strip of woven fabric or paper to said backs, extending partially or entirely throughout the length of said signatures or sections. A number of folded signatures or sections composing a. book have also been secured together by attaching them, by stitches or staples passing through their folds, to a strip or strips of closely-woven fabric, and then applying'glue to the outside of said strip or strips and the exposed portions of the backs of said signatures or sections. In this latter method the glue could not readily be applied until after the signatures or sections had been attached to -said strip or strips, and then did not, as ordinarily applied, permeate the latter and insure a proper juncture of the backs of the signatures or sections to each other and to the said strip or strips.

To obviate the last-named difficulty is the object of my invention; and it consists in the combination, in a book, of-a number of folded signatures or sections Witha strip or strips of open and sufficiently-strong Woven fabric, the signatures or sections being united at their backs to the open fabric and to each other by stitches or wire staples passing through their folds, andthe glue,whicl1 permeates the open fabric and insures a proper juncture or Aunion `for accomplishing this end.

ings, by any of the machines or modes in use p Glue is then applied to the outside of the strip or strips of open fabric and the backs ot' the signatures its signatures or sections are printed or not,

and other circumstances. Y

' In securing together the signatures or seetions of printed books, it is desirable to use but one strip of open fabric `for each book, which may extend partially or wholly throughout the entire length of the backs of the signatures or sections-as shown in Fig. l of the drawings. In securing together the signatures or sections of blank books, it is desirable to use two or more of such strips of open fabric, as shown in Fig. 2 of the drawings. One strip may, however, be used with advantage in any kind of book. After the signatures or sectionshave been attached to said strip or strips of open fabric and the glueV has been applied as described, the side boards may be secured in any suitable andwell-known manner.

Instead of glue, any other suitable, cement maybe employed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isp The combination, in a book,of a number of -folded signatures 0r sections with a strip or In testimony whereof I have hereunto set` lo strips ofl open fabric, the signatures or seemy hand in the presence of two subscribing tions being united at their backs to the open Witnesses.
